      They usually are battery powered, and warn you well in advance when it has to be changed.

        yeah mine gets super slow to actuate when the batteries are low. I change it before each winter.

      if there is a battery failure, you can use a 9V battery to provide temporary power to the lock. so I keep a couple in the garage behind another electronic lock. and if that fails, I’ll borrow a 9V battery from a neighbour
